Mechanical Installation 2-2
Inspect the top and sides of the display for any holes that may allow moisture to enter the
display. If the lift eye bolts are removed, plug the holes with bolts and the rubber sealing
washer which was removed with the eye bolt. Plug and silicone around any hole or opening
that may allow moisture to enter the display.
2.3 Cabinet Display Mounting
Reference Drawing: Mounting Example; Small Line Displays .... Drawing A-101424
Visually check the display mounting structure before beginning the installation process.
Ensure that the structure will provide a straight and square mounting frame for the display.
Height variation in any 4-foot horizontal section must not exceed 1/32-inch. Also, inspect the
mounting frame for areas that might yield once the display is in place. If any problems are
noted, take corrective action before mounting the display.
All small matrix displays must be supported every eight feet with a maximum three foot
overhang on each end of the display. The distribution of these supports is to be symmetrical,
with a minimum of two supports.

Note: These specifications are only accurate for cabinets made with Daktronics channel,
part number HEX-319.
Drawing A-101424 shows an example method of mounting cabinet displays to columns.
Specific project mounting details will be included in Appendix D if applicable. Please
contact Daktronics for additional mounting details and specifications.
It is the responsibility of the installer to ensure the installation will adequately meet local
codes and standards. The mounting hardware and method is also the responsibility of the
installer. Be sure to maintain a minimum of
O-inch clearance between all drain openings in
the base of the sign and the mounting surface.
Any modification of the Daktronics air filtration system must first be approved by Daktronics
engineering staff.
Electrical installation requires access to the inside of the display (refer to Section 3).
2.4 Display Ventilation Requirements (For Enclosed Displays)
i
Any new plans for filtering air in this display must be submitted to Daktronics
engineering staff for evaluation and approval or the warranty will be null and void.
In this display, 12 square inches of unobstructed opening per module is required to ensure
adequate display cooling. Allowances must be made to compensate for the percentage of
screen in the material covering the openings in the enclosed structure. If air must be forced
into the enclosed area, 110 cubic feet per minute must be provided per module (one module =
12" x 24" display active area, or 8 rows x 16 columns of lamps).
